SPECIPICAI'ION fo:ming part of Letters Patent N0. 359,564, dated March 15.- 188'7 Applicntiim filed Jul y 19, 1586. Serial N0. 208,366. (N0 model.)

T0 all whom z'b may c0ncern:

Be it known that I, HENRY B. HAPPE, of Beaver Falls, in the county of Bemer end State of Pennsylvania, have invented a new end useful Improvemenb in Vire-Nail Machines; and I do hereby declare the followi'ng t0 be a full, ulear, and exact; description bhereof, reference beinghad t0 the accornpanyin g drawings, forming parb 0f this specification, in which- Figure 1 is-a plan view of the machine. Fig. 2 is a vertical longitudinal section 011 the line x 00 of Fig. l. Figs. 3, 4, end 5 are enlarged views of he heading die or hamrner end its conneetions. Fig. 6 is a side view of one of the cutters, its head, end slideways. Fig. 7 is an end view end Fig.. 8 is a lan view thereofb Fig. 9 is a plan view of the gripping-dies. Fig. 10 is a froni; elevalzion thereof; end Fig. 11 is a vertical cross=section 011 the line y y of Fig. 10.

Like symbols 0f reference indicate like parts in each.

My invenlien relates t0 an improvemenb 0n lohnt; dass 0f nail-machines in which the wire is passed through the machine from a coil,and

die,which is attached t0 the end of a reciprocating plunger, 4. (Shown in detail in thefigures 0n Ehe t=hird sheet 0f t-he drawings.) This plunger is made with two separated slide-bars connected near their front ends by a link-pin, 5, end has lateral flanges 6, on which it slides on Ehe fmme of the machine. A link, 7, encircles an eccentric wrist-pin, -8, 011 he rnain shafts 9, end connects it with the pin 5 of the The. plunger end die will thus be reciproca-ted once during each revolution of 13116 main shaft, and es tl1e flzxnges 6 of Ehe plunger have theiir bearings both in the rear (und front 0f the mein shaf, the mot;ions of the plunger will be even and will have a straighta end more direct course to the gripping-dies than if the bearing of the head wereat one side only of the main shaft.

It is desirable that tl1e center 0f theshaft 9, driving ehe plnnger whieh heads the nails, shonld be substantiallyin a, line with Ehe wire. Therefore, in order to clear the shafb 9, I curve the plunger, as ab c, so that :it may bridge bhe shafi: either above or below it, as shown in Fig. 1. The parh c connects the rear end froni; flnnges, 6. I am aware thab in blownail machines, whose heading-dies a.re neinated by springs, it has been (zustomary t0 pro vide the plunger with bearing-surfaoes b0th back of end in freut; 01" the aetuating-shaft; but this arrangement has never been had with press-machines 0f the dass to which the rnmchine shown in the dmwings belongs, nor with machines wherein the axis 0f 'he shafb driving the plunger is in substantially tlie same horizontal line with the wir-e 0f which the nails are formed.

Tne gripping-dies 10 end 11 are shown in feet rest on the upper sides of the dies end 011 snnken seats or shoulders ab the rear of the blocks 19. The shoulders ab the rear of t-he blocks keep the caps from slipping These caps are runde distinct in Order 130 leave an open space through whieh-the operaion of the dies may be easily seen fron1 aboVe, end by which access may be had 130 clean them. They are adjusted by bolbs 14, traversing slots in the caps and' entering the block 19, which permits t;he caps to be adjusbed bakward or l'orward, end by serews 15, which rest on the surface of the block end by enabling it to be tilted regulate the degree of pressure 0f the forward flanges in the dies. Since tlre die 11 is nob movable obherwise than for purpose 0f ndjusbment, its eap is sei: so as 130 clamp it tigholy against its seat on the block 19, and the serews 15 are omitted; Du's, as the die 10 must; be capable 0f reciprocation toward and away frdm the ends of its compzrnion, its cap is set by the screws 15 so that the forward flange shall rest 0n but sl1all not clamp the die.

'Ihe die 10 is aetuated by a lever, 16, 0f the seeond dass, wl1ieh is fulerumed zmt d, aud at the0ther end is provideclwith afrietionmoller whieh works in a groove in a cam, 17, 011 the main shaft. "Ihis lever is conneeted with the die 10 by an acljustablepusher-link, 18, whieh bears 011 the end 0f the die, 21s shown in Fig. 1, and is further attached thereto by means 0f a hook 0113i11 (00tshown) whieh engages a hole, e, in the side 0f the die, Fig. 10. By these means the die 10 is aetuatecl so es t0 app1oaeh and recede f10m the stationary die 11.2tt regular intervals. The dies are vertieally adj ustable int0 alignment Witli the wire by means of aset boltorbolts, 20, Fig. 2,which pass through the bed 0f the maehine and engage thebottom 0f the block 19, thus enabling it to be raised 0r lowered. The die 11 is longitudinally adjustable t0 and f r0m its companion die by a set-bolt, 21, the arrangement 0f which is elea-rly sh0wn in Figs. 9 und 10.

'1he cutters 22,which sever the nail after it has been headed, are shown in Figs. l and 2 and in detail in Figs. 6, ztnd 8; E2th of these cutters is fixed to a. moving head,which is mde in separate parts f0r the purpose 0f adjustment.

Figs. 6,-7, und 8 sl1ow oneof the cutters and its head, b0th cutters and heads being identical in construetion.

23 is the bed 0r slide-bloek in whieh the entter-head tmvels. It is Set transversely 0f the machine, but is provided with a tongue, 24, whieh fits in a groove in the bed 0f the machine, and enables the slide-block t0 be mo'ved l0y screws 24 lengthwise 0f the machine f0r the purp0se 01 securing relative alignment of the cutters with eaeh other.

25 is the vertical post 01 carriage-pieee 0f the cutter-head. It has a clovetailed 10wer end 01 f00t, WhiCh fits in a mortised slideway in the slitle-bloek 23, and is held therein by a beveled key 01 grip, 26, which is adj ustable by setsere'ws 27 and 28, 0f which the serews 27 bear again st the side 0f the key, and the se rews 28 pass through slots therein int0 the bed 23.

It will be notieed that the ea-rriage 25 is arranged on the slide-block 23 at the rear 0f the gripping-dies.- 'lhis enables the cutters to be made adjustable toward and awayirom the dies by motion 0f the slide-bloek for the purp0se 0f varying the size 0f the nail-heacls with- 0ut need of eutting or recessing the cutterhead to at1"ord elearanee thereof. The cutters ean therefore be Set very solidly in their heads.

Projecting ab right angles from the side 0f the cztrriage 25 is the cutter-heacl proper, 29,

enters the body 0f the earriage, and is used f0r screwing d0w11 er depressing thecutterhead, and the screw 32 bGZLI'S 011 the top 0f the earriztge and is used f01' raising am]. fixing it.

When the head has thus beei1 properly adjusted it is elainped t0 the earriage by the holt 30. At the base 0f the cutter-head it has a horizontal angular projeetion 0r ehair. whose.

outer side has a shelf 0r recess 0n whieh the cutter-blade 22 rests. 'll1e cutter is cla.mped in place by means 0f a cap, 33, a.nd b0lt 34,

eonstrueted and arranged similarly t0 the cap 12 and holt 14 0f the gripp ing-die 11, bef0re described.

'Ihe eutters L1re reciproeated toward each other t0 se ver the wire by means 0f levers 35,

Figs. 1 and 2, whieh are fulerumed t0 a cross bar or brace, 36, and have at their front ends l'ollerS whieh are in the gro0ves 0f cams 37 on 8 1 toward and away from eaeh other. The journals of the rolls g are fixed, bat the bearings 0f the ro1ls'h are movable and adjustable by setloolts 40. Near the outer end 0f thebat39 is pivoted a link, 41, t0 the free end 0f which is pivoted a cam, 42, having a hand-lever, '43.

In inserting the wire between the rolls the bars 38 and 39 are first opened, as indieated by dotted lines in Fig. 1, the wire is placed, and after the bars 38 and 39 have been closed, so es t0 confine thewire between the rollers, the baxs are loeked by throwing the link 41 0ver thebar 38 ancl turning the czmi-lever, as shdwxi by 1 1o V full lines in Fig. 1. This arrangement enables easy access t0 be had t0 the rollers f0r cleaning them, and when the rollers hexe 0nee been adj usted by the bolts 40 f0r any given size of ends, andare adapted t0 be swung thereon wire the adjustment need not be disturbed x|5 wheu a new c0il 0f the same gage is inserted.

44 is the feed-carriage, whicl1 reciprocates 011 a traek 017 slideway, 45, 'and is actuated by a1ever, 46, whieh is connected by a. pitman,

47, t0 an adjustable eceentrie, 48, 011 the mein 1 20 shaft 9. The lever 46 is pivotally attached to a pivoted dog 0r eatch, 49, 0n the earriage 44, which 11as a eompanion (log, 50, fix0d on the carriage 0p p0site it. The wire lies between these dogs, and,as the free end 0f the lever 46 moves back, it will first; -move the d0g 49 t0 separate it from the part 50 and t0 disengage the wire unt-il the le ver strikes a Ing, 51, 0n the carriage, when the further moti0n 0f the lever Will draw back the carriage.

forward motion 0f the lefrer the dog 49 will first be n10ved toward the d0g 50, so as t0 elamp the wire between their encls, and tlien the 1ever will advance the carriage t0 fed the 011 the 130 wire 130 the machine. The operation is thus repeated, the carria-ge slipping freely past thewire in its back strokes and feeding it in the forward strokes: The feeding action is thns n1ade very certain and regular.

The course of the wire is fron1 the c0il, between the straightening-rolls,between the feeddogs 49 and 50, and bebween the gripping-dies 2md cutters, and the operation of the machine is as follows Snpp0se the cutters 150 be separated and the gripping-dies t0 hold the wire, the end of which projects sligl1tly toward the heading-die. 'Ihe latter then advances, and engaging the projecting en d 0f the wire flat tens it and f0rms a heacl 0n it for thenail,acting 011 the dies as an anvil. Thenas the heading-die recedes,tl1e gripping-dies separateand the feedcarriage moves forward t0 advance the wire a disbance equal t0 the length of a Single nail. Then the cutters approach and sever the wire giving a point t0 the nailwhich is cut 0ff. The gripping-dies then seize the wire, the cutters recede, and the opei-abion is repeated, as just described. The relative periods of motion 0f the several parts are adjusted by timing 0f their primary cams and eecentrics 011 the ma.in shaf.

The advantages ofmy machine consist,principally, in the time and labor saved by the ease in adjusting the seveial parts, paricnlarly the gripping-dies, the cntters, and the feeding and straightening meehanism.
